    Here are the pages from the 1977 Bowditch that concern this device.

    I see by the brass plate in one of the photos the instrument was made
    in Belfontaine Ohio a place near to my heart: I learned to swim at a
    YMCA there in 1946. So let me add $25 to the fund to purchase this
    fascinating device.
    
    BTW and FWIW, the general look of the thing reminds me of a device
    that appeared in earlier editions of Bowditch (c. 1982?)  in their
    listing of sight reduction methods.  As I recall the Bowditch
    description had a picture of the device which appeared to be made of
    three white plastic plates that could be set to make a miniature
    navigational triangle. It looked like you set the two vertical plates
    to LHA and then aligned a third lateral plate with declination on one
    of the vertical plates and latitude on the other and read Hc from the
    lateral plate.
